I would not, I probably use those thick shields and ram the dread into oblivion at the highest speed I can reach.

Does kill me an my crew, but I am certain they put a plague up for us somewhere to comment our heroic action.

I must say this one is just more up my ally big guns, screw missiles and stare the enemy down. Feels so much simpler than fancy missiles and the stuff, just get in aim and shoot, whit a nice grin on your face.

No one you would manage to make it through to hit a Celestial. A celestial's mass drivers alone would rip a battlecruiser to shreds. In fact, it could gut an entire squadron of battlecruisers with ease. You would end up being dust in the face of my flagship.

And though the big guns may be simpler, the Alliance's missiles are advanced and capable, they can engage well outside the typical range of Imperial warships and while Imperial warships might bite hard when they get within gun-range, a modern alliance Vanguard-Class battlecruiser could probably soften a Empyrean Sovereign enough so that when they get gun-to-gun, the Vanguard could still do its job

Well you really can't ram in this universe. These ships are moving at 2.5% the speed of light in combat and are arching pass each other at high speeds and firing like mad. Ramming really won't work. Sorry
